A mechanic uses a screw driver to install a ¼-20 UNC bolt into a mechanical brace. What is the mechanical advantage of the system? What is the resistance force if the effort force is 5 lb.
Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs

You’re mapping out the logical relations of a database, and you notice that one of your tables will have a pair of child records for every record created in the parent entity. What type of relationship do these tables have?
A. One-to-many
B. Pair of one-to-many relationships
C. Many-to-Manu
D. One-to-one
The type of relationship that these tables have is (B), Pair of one-to-many relationships.
What is one-to-many relationships?A one-to-many relationship is a type of relationship between two tables in a database where one record in the parent table can have multiple child records in the child table. In this case, one record in the parent table will have a pair of child records in the child table, so the relationship between the two tables is a pair of one-to-many relationships.
For example, a table of employees could have a one-to-many relationship with a table of dependents. Each employee could have multiple dependents, so each record in the employees table would have a pair of child records in the dependents table.

A) Having low initial costs
B) Using a server for a short amount of time
C) Not needing to manage physical servers
D) Having complete control over your physical infrastructure
Answer:
The correct options are A, B and C.
Explanation:
Infrastructure as a Service is simply a service which affords businesses the option of outsourcing their Hardware technology needs especially as it relates to computing.
It is a cloud-based service. Common examples include but are not limited to
Amazon Web Services (AWS)Google Compute Engine (GCEDigitalOcean Microsoft AzureAs highlighted above, they offer small business the advantage of high-quality IT infrastructure at very affordable costs. Businesses that want to shed the cost of their IT infrastructure whilst increasing their computing powers are most likely to purchase these services. E.g. start-ups or companies reviewing/implementing a cost restructuring.
Of course, one of the disadvantages of (IaaS) is that companies have to forfeit complete control of their physical infrastructure. Furthermore, because it is online, computing speeds may be dampened by internet speed.

using substitution what is the value for x for the equations 2x+y=-3 and y=4x+6
Answer:
[tex]x = \frac{-3}{2}[/tex]
Explanation:
Given
2x + y = -3
y = 4x + 6
Required
Find the value of x
2x + y = -3 --- Equation 1
y = 4x + 6 --- Equation 2
Substitute 4x + 6 for y in equation 1.
So, equation 1 becomes
[tex]2x + 4x + 6 = -3[/tex]
[tex]6x + 6 = -3[/tex]
Subtract 6 from both sides
[tex]6x + 6 - 6 = -3 - 6[/tex]
[tex]6x = -9[/tex]
Divide both sides by 6
[tex]\frac{6x}{6} = \frac{-9}{6}[/tex]
[tex]x = \frac{-9}{6}[/tex]
Simplify fraction
[tex]x = \frac{-3}{2}[/tex]
Hence, the value of x is [tex]x = \frac{-3}{2}[/tex]

Explanation:
When checking for a no-start concern, you notice that an engine has no spark. Technician A says to turn on the ignition (engine off) and, using a DMM, find out how much battery voltage is available at the negative terminal of the ignition coil. Technician B says the DMM reading should fluctuate, indicating that the primary coil current is being turned on and off. Who is correct?
A. Neither Technician A nor B
B. Both Technicians A and B
C. Technician B
D. Technician A
Answer:
Option(C) is the correct answer to the given question.
Explanation:
Since overall the On-Board Diagnostics of the level 2 the computer systems need to evaluate the cause of the engine failures .The malfunction significantly increases in the fuel consumption, so that we can detecting the error code in the vehicle.
If we starting the engine as well as by using the DMM, we'll see how much battery voltage it is at the negative ignition coil node.If the spark module is faulty and no ignition coils can fire so all the engines are working that's why all the other option are incorrect .Write code using the range function to add up the series 99, 98, 97,...

A. Design an algorithm that takes 2 integers input from users in 2 variables, without using any other variable swap the values. Design its flow chart as well.
Answer:
The algorithm is as follows
Start Accept Input1 and Input2 Input1 = Input1 + Input2 Input2= Input1- Input2 Input1= Input1- Input2 Print Input1 Print Input2 StopSee attachment for Flowchart
Line 1 and 8 of the algorithm starts and stops the algorithm
Line 2 accepts the two integer variables (input1 and input2)
Take for instance input1 = 5 and input2 = 4
Line 3 increases input1 by input2
At this point, Input1 = 5 + 4 = 9
Line 4 subtracts input2 from input1 and saves it in input2
i.e. Input2 = 9 - 4 = 5
Note that, the value of input2 has changed to the initial value of Input1
Line 5 subtracts input2 from input1 and saves it in input1
i.e. Input1 = 9 - 5 = 4
Note that, the value of input1 has changed to the initial value of Input2
Line 6 and 7 prints the new values of input1 and input2
The flowchart does the same thing as the algorithm; the only difference is that it uses lines and shapes to depict flow of program
The flowchart was designed using Microsoft Office Word
